[0001] The present invention concerns the field of laundry washing techniques.
[0002] In particular, the present invention refers to a treating agents dispenser in a laundry
washing machine.
BACKGROUND ART
[0003] Nowadays the use of laundry washing machines, both "simple" laundry washing machines
(i.e. laundry washing machines which can only wash and rinse laundry) and laundry
washing-drying machines (i.e. laundry washing machines which can also dry laundry),
is widespread.
[0004] In the present description the term "laundry washing machine" will refer to both
simple laundry washing machine and laundry washing-drying machine.
[0005] Laundry washing machines generally comprise an external casing, or cabinet, provided
with a washing tub which contains a rotatable perforated drum where the laundry is
placed. A loading/unloading door ensures access to the drum.
[0006] Laundry washing machines typically comprise a treating agents dispenser arranged
to the frontal side wall of the cabinet, opportunely in an upper region of the latter,
positioned above the tub for the introduction of water and treating agents (i.e. detergent,
softener, rinse conditioner, etc.) into the tub.
[0007] Known treating agents dispensers comprise one or more reservoirs, or compartments,
adapted to be filled with at least one treating agent and one or more respective water
conveying lines for conveying water to the compartments.
[0008] Water conveying lines are typically realized in a water distributor placed above
the compartments. The water distributor is opportunely shaped to define channels provided
with apertures allowing water coming from the water main to fall down in the underlying
compartments.
[0009] Known treating agents dispensers are advantageously connectable to a water source
via dedicated controllable supply valves. Typically, the water source adducts cold
water to the treating agents dispenser. Other known treating agents dispensers are
connectable to a warm or hot water source.
[0010] The cabinet of the laundry washing machine typically has at the rear an access for
allowing a connection to the water/s source/s and said supply valves are arranged
closed to, or fixed to, the inner side of the rear wall of the cabinet.
[0011] One or more connecting pipes are then utilized to connect at one end said valves
and at an opposite end the water distributor of the treating agents dispenser.
[0012] At this purpose, water distributors of known type are provided with horizontal inlets
connectors rearwardly projecting from the body of the water distributor which are
connected to said opposite ends of the connecting pipes.
[0013] Furthermore fastening means, for example clamp, are used to secure ends of the pipes
and valves and/or inlets of the water distributor tightly together.
[0014] However, the system for supplying water above described belonging to the known art
poses some drawbacks.
[0015] A first drawback posed by the known technique is constituted by the fact that the
system for supplying water is cumbersome.
[0016] In fact, said arrangement comprises said treating agents dispenser, horizontal inlets
connectors rearwardly projecting from the water distributor, connecting pipe/s and
valves wherein all these elements are substantially aligned from the front side of
the cabinet to the rear side of the same.
[0017] In particular, the connection system between valves and the water distributor comprising
connecting pipe/s requires a relevant space at the rear side of the laundry washing
machine.
[0018] This firstly negatively affects the size of the laundry washing machine, in particular
the distance between the front side and the rear side of the laundry washing machine.
[0019] This also negatively affects manufacturing costs of the treating agents dispenser
and/or of the drawer of the laundry washing machine.
[0020] On the other hand, a prefixed distance between the front side and the rear side of
the laundry washing machine, for example size required by standards, limits the size
of the treating agents dispenser and in particular of the drawer.
[0021] The main object of the present invention is therefore to overcome said drawbacks.
[0022] In particular, it is one object of the present invention to provide a laundry washing
machine having a treating agents dispenser with reduced size compared to laundry washing
machines of known type.
[0023] It is another object of the invention to provide a laundry washing machine having
a higher capacity of the drawer compared to laundry washing machines of known type
of the same size.
[0024] It is a further object of the invention to provide a laundry washing machine having
a treating agents dispenser with reduced complexity compared to laundry washing machines
of known type.

of a liquid into a supply pipe (not shown) fluidly connecting the treating agents
dispenser 20 and the tub 3.
[0074] It is underlined that in the present application saying that a first component is
"fluidly connected" to a second component means that a fluid can flow from the first
component to the second component and vice versa.
[0075] The first compartment 23a of the drawer 22 is fluidly connected to the bottom of
the housing 21 through an aperture 26 defined at the rear of the first compartment
23a.. The aperture 26 is adapted to allow the flowing of a liquid into the supply
pipe fluidly connecting the treating agents dispenser 20 and the tub 3.
[0076] The other compartments 23b, 23c and 23d of the drawer 22 are preferably fluidly connected

[0077] The treating agents dispenser 20 further comprises a water distributor 35, associated
to the housing 21 and placed above the drawer 22 in such a way to allow the flowing
of water to one or more of said compartments 23a, 23b, 23c, 23d.
[0078] The water distributor 35 comprises one or more water conveying lines 120a, 120b,
120c, 120d, 120e, as illustrated in Figure 8, adapted for selectively conveying water
to one or more of said compartments 23a, 23b, 23c, 23d.
[0079] In the preferred embodiment herewith illustrated and described, there are five water
conveying lines 120a, 120b, 120c, 120d, 120e.
[0080] The water conveying lines 120a, 120b, 120c, 120d, 120e are opportunely shaped to
create channels 70 adapted for conveying water to one or more of said compartments
23a, 23b, 23c, 23d of the drawer 22 when the latter is placed in its closed operative
position.
[0081] At this purpose, the channels 70 are provided with outlets 29 facing the underlying
compartments 23a, 23b, 23c, 23d that allow the passage of the water from the water
distributor 35 to the underlying compartments 23a, 23b, 23c, 23d. The water conveying
lines 120a, 120b, 120c, 120d, 120e comprise respective inlets 121a, 121b, 121c, 121d,
121e through which water may flow.
[0082] Inlets 121a, 121b, 121c, 121d, 121e are preferably arranged close to the rear side
39 of the distributor 35.
[0083] In the preferred embodiment herewith illustrated and described, there are five water
conveying lines 120a, 120b, 120c, 120d, 120e and six channels 70.
[0084] In different embodiments, the number and/or the shape of the water conveying lines
and/or of the channels could be different according, in particular, to the number
of compartments of the drawer.
[0085] The water distributor 35 preferably comprises a lower part 35a and an upper closing

washing machine 1 is installed. The first water source E is preferably a source for
the adduction of cold water.
[0088] In the embodiment illustrated in the enclosed Figures the water distributor 35 is
further apt to be connected to a second external water source E'. The second water
source E' is preferably a source of warm or hot water. The second water source E'
can be fed with warm or hot water obtained, for example, by a solar thermal collector.
[0089] The laundry washing machine 1 is therefore provided with a first inlet duct 7a and
a second inlet duct 7b for the hydraulic connection to the first water source E and
the second water source E', respectively.
[0090] At this purpose, preferably the rear side wall 2b of the cabinet 2, as illustrated
in Figure 3, preferably comprises a first aperture 11 which receives the first inlet
duct 7a and a second aperture 12 which receives the second inlet duct 7b.
[0091] The first and second inlet ducts 7a, 7b are preferably associated to a valves assembly
40.
[0092] The valves assembly 40 preferably comprises five controllable valves 40a, 40b, 40c,
40d and 40e, preferably of the electromagnetic type, opportunely controlled by the
control unit.
[0093] Preferably, first, second, fourth and fifth controllable valves 40a, 40b, 40d and
40e are fluidly connected to the first inlet duct 7a and the third controllable valve
40c is fluidly connected to the second inlet duct 7b.
[0094] The valves assembly 40 allows adduction of cold and/or hot water from the water sources
E, E' to the conveying lines 120a, 120b, 120c, 120d, 120e of the distributor 35, as
better described later.
[0095] The valves assembly 40 is preferably fixedly associated to the cabinet 2. Preferably
the valves assembly 40 is fixedly associated to the inner side of the vertical rear
side wall 2b.
[0096] According to an aspect of the invention, the water distributor 35 comprises one or
more inlet connectors 36a, 36b, 36c, 36d and 36e fluidly connected to said one or
more water conveying lines 120a, 120b, 120c, 120d, 120e and the respective inlets
121a, 121b, 121c, 121d, 121e.
[0097] Inlet connectors 36a, 36b, 36c, 36d and 36e are opportunely connected to the valves
assembly 40 through respective pipes 34a, 34b, 34c, 34d and 34e.
[0098] Preferably, the first inlet connector 36a is connected through the first pipe 34a
to the first controllable valve 40a, the second inlet connector 36b is connected through
the second pipe 34b to the second controllable valve 40b, the third inlet connector

[0099] Cold and/or hot/warm water is conveyed to one or more of said compartments 23a, 23b,
23c, 23d of the drawer 22 by selectively activating one or more of the valves 40a,
40b, 40c, 40d, 40e and making the water flowing through the respective pipe 34a, 34b,
34c, 34d, 34e and water conveying line 120a, 120b, 120c, 120d, 120e up to the outlets
29.
[0100] In other preferred embodiments, not illustrated, in the drawer there can be more
than four compartments, and in the water distributor there can be more than six channels,
each one fluidly communicating with a different region of the water distributor which
is positioned in such a way to be placed above a different compartment of the drawer
when the latter is placed in its closed operative position; also in this case, by
acting on the controllable valves, it is possible to selectively feed a desired channel
with water coming from the water source.
[0101] In further embodiments, not illustrated, in the drawer there can be less than four
compartments, even just one, and in the water distributor there can be less than six
channels, each one fluidly communicating with a different region of the water distributor
which is positioned in such a way to be placed above a different compartment of the
drawer when the latter is placed in its closed operative position; also in this case,
by acting on the controllable valves, it is possible to selectively feed a desired
channel with water coming from the water source.
[0102] According to an aspect of the invention, the inlet connectors 36a, 36b, 36c, 36d,
36e preferably each comprises a projecting body 136a, 136b, 136c, 136d, 136e extending
along a main axis X which is inclined with respect to the sliding axis S.
[0103] More preferably, the projecting body 136a, 136b, 136c, 136d, 136e extends downwardly
and preferably along a main axis X which is perpendicular with respect to the sliding
axis S.
[0104] Preferably, the main axis X lies in the vertical, or substantially vertical, plane
when the treating agents dispenser 20 is mounted in an operational position.
[0105] More preferably, the main axis X is perpendicular to the horizontal plane when the
treating agents dispenser 20 is mounted in an operational position and the water distributor
35 lies in the horizontal plane.
[0106] The projecting bodies 136a, 136b, 136c, 136d, 136e of the inlet connectors 36a, 36b,
36c, 36d, 36e are preferably cylindrically shaped. This enhances connection of the
pipes 34a, 34b, 34c, 36d, 34e to the inlet connectors 36a, 36b, 36c, 36d, 36e.
[0107] More preferably, the projecting bodies 136a, 136b, 136c, 136d, 136e of the inlet
connectors 36a, 36b, 36c, 36d, 36e comprises an annular projecting rib 137a. This
further enhances connection of the pipes 34a, 34b, 34c, 36d, 34e to the inlet connectors
36a, 36b, 36c, 36d, 36e.
[0108] In preferred embodiments, connection of the pipes 34a, 34b, 34c, 36d, 34e to the
inlet connectors 36a, 36b, 36c, 36d, 36e comprises fastening means, for example clamps.
Clamps preferably tighten ends of the pipes 34a, 34b, 34c, 36d, 34e around the projecting
bodies 136a, 136b, 136c, 136d, 136e of the inlet connectors 36a, 36b, 36c, 36d, 36e.
[0109] Preferably, the valves assembly 40 is arranged vertically below the water distributor
35, more preferably just below the free ends of the inlet connectors 36a, 36b, 36c,
36d, 36e.
[0110] More generally, the valves assembly 40 is arranged spaced apart from the free ends
of the inlet connectors 36a, 36b, 36c, 36d, 36e along the main axis X.
[0111] Such arrangement allows to minimize the interspace between the treating agents dispenser
20 and the valves assembly 40 and allows the assembly of the treating agents dispenser
20 closer to the valves assembly 40 compared to known systems.
[0112] Advantageously, the size of the laundry washing machine 1, for example the distance
between the front side wall 2a and the rear side wall 2b, may be reduced compared
to known systems.
[0113] On the other hand, while maintaining the same external size of the laundry washing
machine 1, it is possible to increase the size of the treating agents dispensers 20,
in particular of the drawer 22, compared to known systems.
[0114] This helps to adopt a better design solution for the treating agents dispensers 20
and/or for the drawer 22.
[0115] Said arrangement, furthermore, allows to minimize the length of the pipes 34a, 34b,
34c, 34d, 34e and therefore to reduce the complexity of the laundry washing machine
1.
[0116] Pipes 34a, 34b, 34c, 34d, 34e substantially comprise short L-shaped pipes portion.
Pipes 34a, 34b, 34c, 34d, 34e preferably comprise flexible pipes, more preferably
plastic flexible pipes.
[0117] Advantageously, the arrangement according to the invention allows to reduce costs
of production and assembly time of the pipes and/or of the treating agents dispensers
20.
[0118] Furthermore, arrangement of the inlet connectors 36a, 36b, 36c, 36d, 36e perpendicularly
with respect to the plane of the distributor 35 facilitates the manufacturing process
of the distributor 35, in particular when a molding process is involved.
[0119] The inlet connectors 36a, 36b, 36c, 36d, 36e are preferably integrally made with
the water distributor 35, more preferably integrally made with the lower part 35a
of the water distributor 35.
[0120] The water distributor 35 and/or the inlet connectors 36a, 36b, 36c, 36d, 36e are
preferably made of Polypropylene (PP).
[0121] In the preferred embodiment above illustrated and described, the projecting bodies
136a, 136b, 136c, 136d, 136e of the inlet connectors 36a, 36b, 36c, 36d, 36e are parallel
one to the other and extend along the main axis X.
[0122] In different preferred embodiments, inlet connectors may extend along different axis
one to the other and each extending along a respective axis which is preferably inclined

[0123] Figures 11 to 13 illustrate a further embodiment of a water distributor 235 of a
treating agents dispenser according to the present invention.
[0124] The water distributor 235 comprises three water conveying lines 320a, 320b, 320c
adapted for selectively conveying water to one or more of the compartments of a drawer.
[0125] The water conveying lines 320a, 320b, 320c are opportunely shaped to create channels
adapted for conveying water to one or more of said compartments of the drawer when
the latter is placed in its closed operative position.
[0126] The channels are provided with outlets facing the underlying compartments that allow
the passage of the water from the water distributor 235 to the underlying compartments.
[0127] The water distributor 235 preferably comprises a lower part 235a and an upper closing
part 235b structured for being reciprocally coupled to form the water distributor
235. The two parts 235a, 235b are preferably coupled by welding and/or glueing and/or
joint.
[0128] The water distributor 235 preferably has a substantially flattened configuration.
The water distributor 235 preferably extends along the sliding axis S and preferably
lies in the horizontal, or substantially horizontal, plane when the treating agents
dispenser is mounted in an operational position.
[0129] According to the invention, the water distributor 235 comprises three inlet connectors
436a, 436b, 436c fluidly connected to said water conveying lines 320a, 320b, 320c.
[0130] According to an aspect of the invention, the inlet connectors 436a, 436b, 436c, preferably
each comprises a projecting body 536a, 536b, 536c extending along a respective axis
X, X, X1 which is inclined with respect to the sliding axis S.
[0131] More preferably, the projecting bodies 536a, 536b of the first two inlet connectors
436a, 436b extend downwardly and preferably along a main axis X which is perpendicular
with respect to the sliding axis S.
[0132] More preferably, the projecting body 536c of the third inlet connector 436c extends
downwardly and preferably along an axis X1 which is inclined with respect to the sliding
axis S.
[0133] Preferably, the axes X, X1 lie in the vertical, or substantially vertical, plane
when the treating agents dispenser is mounted in an operational position.
[0134] More preferably, the axes X, X1 are perpendicular to the horizontal plane when the
treating agents dispenser is mounted in an operational position and the water distributor
235 lies in the horizontal plane.
[0135] According to an aspect of the present embodiment, the inlet connectors 436a, 436b,
436c are integrally made as a separate unit 500 which is coupled to the water distributor
235.
[0136] Preferably, the unit 500 is sandwiched between the two parts 235a, 235b of the water
distributor 235.
[0137] The unit 500 preferably then comprises interconnecting portion 550a, 550b, 550c which
fluidly connect the inlet connectors 436a, 436b, 436c to the water conveying lines
320a, 320b, 320c.
[0138] The interconnecting portion 550a, 550b, 550c are preferably integrally made with
the inlet connectors 436a, 436b, 436c.
[0139] The unit 500 is preferably arranged close to the rear side 239 of the distributor
235.
[0140] This preferred embodiment achieves all the advantages above described for the previous
embodiment.
[0141] It has thus been shown that the present invention allows all the set objects to be
achieved. In particular, it makes it possible to realize a laundry washing machine
having a treating agents dispenser with reduced size compared to laundry washing machines
of known type.
[0142] It is underlined that the laundry washing machines illustrated in the enclosed figures
are of the front-loading type; however it is clear that the system according to the
invention can be applied as well to a top-loading washing machine, substantially without
any modification.
[0143] While the present invention has been described with reference to water conveying
lines adapted for conveying water to one or more compartments of the drawer, it should
be noted that the present invention is not limited to this specific embodiment but
can be extended to other embodiments.
[0144] In a different embodiment, for example, a water conveying line of the water distributor
may be opportunely shaped to define a by-pass line.
[0145] The by-pass line preferably allows the flowing of water into the tub without entering
the compartments of the drawer.
[0146] In a further different embodiment, for example, a water conveying line of the water
distributor may be opportunely shaped to preferably allow the flowing of water to
a reservoir/container of a water softening device of the laundry washing machine.
[0147] The water softening device advantageously removes calcium, magnesium and/or certain
other metal cations in hard water before it reaches the compartments of the water
distributor and/or before it is conveyed directly into the tub. The water softening
device advantageously comprises water softening products, such as salt, introduced
into the reservoir for regenerate the softener agents provided in a further reservoir.
[0148] In a preferred embodiment, the container for the water softening products is preferably
supported by the drawer.
[0149] In further preferred embodiments, the container for the water softening products
may be preferably supported by the supporting structure of the treating agent dispenser.
[0150] In other preferred embodiments, the container for the water softening products may
be external to the treating agents dispenser.
[0151] While the present invention has been described with reference to the particular embodiments
shown in the figures, it should be noted that the present invention is not limited
to the specific embodiments illustrated and described herein; on the contrary, further
variants of the embodiments described herein fall within the scope of the present
invention, which is defined in the claims.
